Benefits
-
Reliable sealing ensured by one single sealing element (the diaphragm) which provides hermetic sealing to atmosphere and absolutely tight shut-off. The specially enclosed diaphragm ensures long service life and high operating reliability. -
Balanced diaphragm suspension for increased functional reliability of the diaphragm -
Maintenance-free: All functional parts are located outside the fluid. -
High level of reliability with thrust bearing minimising the closing torques required | -
Optimised long-term operation: The position indicator with integrated stem protection prevents the ingress of contaminants. -
High level of reliability: The valve hydraulics without dead volume ensure optimum conditions for high-purity fluids. -
Long service life: The diaphragm support increases valve life and extends the pressure limit of the diaphragm. -
The SISTOMaXX diaphragm material and the body material 1.4409 meet the recommendations of the German Environment Agency (elastomers guideline) and DVGW Worksheet W270. |
